Description

Technical Field

[0001] The utility model relates to the technical field of edge-sealing hot-melt adhesive production, in particular to a filling device for edge-sealing hot-melt adhesive production. Background Art

[0002] Hot melt adhesive is a plastic adhesive that is solid at room temperature and can quickly bond after being heated and melted. It is low-cost and does not consume any solvent, avoiding the disadvantages of deformation, dislocation and shrinkage of the adherends due to the presence of solvents, which helps to reduce costs and improve product quality. The physical state of hot melt adhesive changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and odorless, and is an environmentally friendly chemical product. Filling equipment is required in the production process of hot melt adhesive.

[0003] After searching, announcement number CN216837083U discloses a filling equipment for hot melt adhesive production, including a filling box, a cavity and a stirring assembly. A motor is fixedly installed on the top of the filling box, and a stirring assembly is movably installed on the output end of the motor. A control button is fixedly installed on one side of the filling box, and a power jack is fixedly provided at the bottom of the control button. A cavity is fixedly provided at the output end of the filling box, a support assembly is fixedly installed at the bottom of the cavity, and a moving assembly is movably installed on the top of the support assembly. The utility model has a stirring assembly movably installed at the output end of the motor, and can open the sealing cover and use the liquid inlet pipe to add hot melt adhesive liquid into the filling box, then use the constant temperature heating plate to heat the hot melt adhesive liquid at a constant temperature to prevent the hot melt adhesive from solidifying, and then use the motor to drive the stirring paddle to stir the hot melt adhesive liquid to ensure the normal operation of the hot melt adhesive liquid filling operation; its defect is that: although the above patent can use the constant temperature heating plate to heat the hot melt adhesive liquid at a constant temperature to prevent the hot melt adhesive from solidifying, the transmission path of the hot melt adhesive liquid is not provided with a heating structure. Once the device stagnates, the hot melt adhesive liquid in the transmission pipe will solidify, making it difficult to carry out subsequent filling work. Therefore, it is particularly important to improve the existing filling equipment and design a new edge-sealed hot melt adhesive production filling equipment to solve the above technical defects and improve the practicality of the overall filling equipment.

[0023] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] Example:

[0025] See also Figures 1-4 , the utility model provides a technical solution:

[0026] A filling device for producing edge-sealing hot melt adhesive includes a filling machine body 1, a support frame 2 is provided at the bottom of the filling machine body 1, a placement platform 3 is provided on the top of the support frame 2, a delivery pipe 4 is provided outside the filling machine body 1 and above the placement platform 3, a filling pipe 5 is provided outside the delivery pipe 4, a heating assembly 6 is provided outside the filling pipe 5, the heating assembly 6 is connected to the filling pipe 5 via a connecting shell 7, and the filling pipe 5 is connected to the delivery pipe 4 via a connecting assembly 8;

[0027] The heating assembly 6 is used to heat the filling tube 5, and the heating assembly 6 consists of a heating tube 9, a water storage tank 10, a heating plate 11 and a circulation pump 12. The heating tube 9 is located outside the delivery tube 4 and inside the connecting shell 7. The water storage tank 10 is located outside the connecting shell 7. The heating plate 11 is located inside the water storage tank 10. The circulation pump 12 is located outside the water storage tank 10.

[0028] The connecting assembly 8 is used to quickly connect the filling tube 5 to the delivery tube 4 .

[0029] Furthermore, the heating tube 9 is designed with a spiral structure on the outside of the filling tube 5, and the two ends of the heating tube 9 are respectively connected to the water tank 10 and the output end of the circulation pump 12. The spiral structure design of the heating tube 9 can increase the flow time of the liquid inside the water tank 10 into the heating tube 9, so that the heated liquid and the heating tube 9 have a better heat delivery effect, and the heating tube 9 is heated. At the same time, the spiral structure design can increase the contact area with the filling tube 5, so that the filling tube 5 can be effectively heated and insulated, preventing the hot melt adhesive remaining in the filling tube 5 from solidifying when not filled, blocking the filling tube 5, and affecting the filling of the hot melt adhesive.

[0030] Among them, the input end of the circulation pump 12 extends to the interior of the water tank 10, and an insulation chamber is opened inside the connecting shell 7 and outside the heating tube 9. The interior of the insulation chamber is filled with inert gas. When the heating tube 9 heats and insulates the filling tube 5, the insulation chamber and the inert gas inside it can increase the insulation effect of the connecting shell 7 and reduce heat loss.

[0031] Secondly, the connecting assembly 8 consists of a sleeve 13, a receiving groove 14, a limit block 15 and a compression spring 16. The sleeve 13 is located at the top of the connecting shell 7 and on the outside of the conveying pipe 4. The receiving groove 14 is opened inside the sleeve 13. The two sets of limit blocks 15 are both slidably connected to the inside of the receiving groove 14. The compression spring 16 is located on the outside of the limit block 15. When the filling tube 5 is used for a long time and needs to be cleaned and maintained, the connecting assembly 8 can easily remove the filling tube 5 from the outside of the conveying pipe 4, clean the impurities inside the filling tube 5, and prevent it from affecting the use of the filling tube 5.

[0032] Furthermore, a sliding groove is provided inside the accommodating groove 14 and on the outside of the limit block 15. The internal structure size of the sliding groove is designed to correspond to the external structure size of the limit block 15. The limit block 15 is connected to the compression spring 16 through the sliding groove. The limit block 15 is slidably connected to the sliding groove so that the limit block 15 can be connected to the compression spring 16. The compression spring 16 cooperates with the sliding groove to drive the limit block 15 to move. Two groups of clamping blocks 20 are provided at one end of the filling tube 5 close to the sleeve 13. The clamping block 20 is connected to the limit block 15. The clamping block 20 is limited to the inside of the accommodating groove 14 by the limit block 15, so that the filling tube 5 can be connected to the accommodating groove 14.

[0033] Furthermore, a sliding rod 17 is provided at one end of the limit block 15 away from the compression spring 16, and the sliding rod 17 is slidably connected to the accommodating groove 14 away from the limit block 15. The limit block 15 is connected to the accommodating groove 14 through the sliding rod 17. The sliding rod 17 is slidably connected to the accommodating groove 14 so that the limit block 15 can be connected to the accommodating groove 14. When the limit block 15 is displaced, it can be guided by the sliding rod 17 to prevent it from being offset.

[0034] Furthermore, a connecting tube 18 is provided at one end of the sleeve 13 close to the filling tube 5. The external structure and size of the connecting tube 18 are designed to correspond to the internal structure and size of the filling tube 5, and multiple sets of sealing rings 19 are provided on the outside of the connecting tube 18 and the inside of the filling tube 5. When the filling tube 5 is connected to the sleeve 13, the connecting tube 18 can be connected to the filling tube 5, so that the hot melt adhesive can be introduced into the interior of the filling tube 5. When the connecting tube 18 is connected to the filling tube 5, the multiple sets of sealing rings 19 can increase the sealing of the connection to prevent liquid leakage.

[0035] In this embodiment, the implementation scenario is specifically as follows: in actual use, the heating plate 11 is started to heat the liquid inside the water tank 10, and the circulating pump 12 is started to introduce the liquid inside the water tank 10 into the interior of the heating tube 9. The spiral structure design of the heating tube 9 can increase the flow time of the liquid inside the water tank 10 into the heating tube 9, so that the heated liquid and the heating tube 9 have a better heat delivery effect, and the heating tube 9 is heated. At the same time, the spiral structure design can increase the contact area with the filling tube 5, so that the filling tube 5 can be effectively heated and insulated to prevent the hot melt adhesive remaining in the filling tube 5 from solidifying when not filled, blocking the filling tube 5 and affecting the filling of the hot melt adhesive. When the filling tube 5 needs to be disassembled, the filling tube 5 is rotated to The clamping block 20 is displaced and displaced from the outside of the limit block 15, so that the filling tube 5 can be displaced from the inside of the accommodating groove 14, and the filling tube 5 is disassembled. When the filling tube 5 needs to be installed, the filling tube 5 is connected to the connecting tube 18, so that the clamping block 20 can be displaced to the inside of the accommodating groove 14, and the filling tube 5 is rotated to drive the clamping block 20 to displace and contact the limit block 15. The compression spring 16 cooperates with the sliding groove to drive the limit block 15 to displace, and the clamping block 20 is connected to the limit block 15. The clamping block 20 is limited to the inside of the accommodating groove 14 by the limit block 15, so that the filling tube 5 can be connected to the accommodating groove 14. Compared with the existing filling equipment, the utility model can improve the overall practicality of the filling equipment through design.
